How do I start/stop the movement of transform.Translate() if a certain animation is playing in the animator?

Hi, I'm hoping somebody can help! I've spent countless hours trying to do such a simple task. All I'm trying to do is move my enemy character with transform.Translate(), but ONLY when the "Walk" animation is active/playing in the Animator.

Here's my Script:

     private Transform player;
     public Animator anim;
     public Transform head;

     public Slider enemyHealthBar;
     public bool shouldMove = false;


     void Start () 
     {
         anim = GetComponent<Animator>();
         player = GameObject.FindWithTag("Player").GetComponent<Transform>();   
     }

     void Update () 
     {
         if(shouldMove == false)
         {
             this.transform.Translate(0f,0f,0f);
         }

         else
         {
             this.transform.Translate(0,0,0.035f);
         }
         
     //************Check Animation and Pause Movement for all except "Walk"**************//

         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Idle1")) 
         {
             shouldMove = false;
         }
         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Attack"))
         {
             shouldMove = false;
         }
         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Magic Attack"))
         {
             shouldMove = false;
         }
         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Magic Attack2"))
         {
             shouldMove = false;
         }        
         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Magic Attack3"))
         {
             shouldMove = false;
         }
         if(this.anim.GetCurrentAnimatorStateInfo(0).IsName("Walk"))
         {    
         shouldMove = true;    //I ONLY WANT TO transform.Translate() if this animation is playing.
         }
         

         if (enemyHealthBar.value <= 0) 
         {
             return;
         }



         Vector3 direction = player.position - this.transform.position;
         direction.y = 0;
         float angle = Vector3.Angle(direction, head.up);

         if(Vector3.Distance(player.position, this.transform.position) < 10 && angle < 100 )
         {

             this.transform.rotation = Quaternion.Slerp(this.transform.rotation,
                 Quaternion.LookRotation(direction), 0.1f);

             anim.SetBool("NecIsIdle",false);



             if(direction.magnitude > 2.7f && Time.timeScale == 1)
             {
                 anim.SetBool("NecIsWalking",true);
                 anim.SetBool("NecIsAttacking",false);
             }
             else
             {
                 anim.SetBool("NecIsAttacking",true);
                 anim.SetBool("NecIsWalking",false);
             }
         }
         else
         {
             anim.SetBool("NecIsIdle", true);
             anim.SetBool("NecIsWalking", false);
             anim.SetBool("NecIsAttacking", false);
         }

     }


     void OnTriggerEnter(Collider other)
     {
         if(other.tag == "FireBall")
         {
             anim.SetTrigger("NecMA2");
         }
     }

Obviously, I'm new to scripting! Any help would be greatly appreciated, thanks!
